How do you find lasting love in today's world? For documentary filmmaker Zoe (Lily James), swiping right to find Mr Right has only delivered bad dates and funny anecdotes, much to her opinionated mother Cath's (Emma Thompson) dismay. For her childhood friend and neighbour Kazim (Shazad Latif), the answer is to follow his parents' example and opt for an assisted marriage with a bright and beautiful bride from Pakistan. As Zoe films his hopeful journey from London to Lahore to marry a stranger, chosen by his parents, she begins to wonder if she might have something to learn from a different approach to finding love.
